The L‑Acoustics LA4 is a professional 2U amplified controller designed to drive and protect L‑Acoustics loudspeakers with repeatable, high‑fidelity results. A 32‑bit/96 kHz DSP platform feeds four channels of clean power, delivering up to 1000 W per channel at 4 Ω with generous headroom and low distortion. A comprehensive library of factory presets covers passive and active loudspeaker modes, while flexible input‑to‑output matrixing streamlines system design and deployment.
LA Network Manager integration enables rapid setup, system‑wide monitoring, advanced EQ, grouping and alignment. Dual Ethernet ports support redundant networking for robust, fail‑safe operation. L‑DRIVE protection continuously manages excursion and thermal conditions to safeguard components at high SPLs. An optional AES/EBU input card minimises latency for time‑critical applications. With a universal 120/230 V power supply and low acoustic noise, the LA4 suits both touring racks and fixed installations where quiet operation is essential.
Ideal for front‑of‑house systems, fills and distributed audio in venues, theatres, houses of worship and rental inventories seeking reliable performance and consistent tonal balance.
